2PSK调制与解调matlab仿真，包括高斯信道awgn，误码率分析(2PSK modulation and demodulation matlab simulation, including the Gaussian channel awgn, bit error rate analysis)

张正友标定法，读取张正友的数据处理。在simon的基础上添加了少量注释，改正了新版本levenberg-marquardt不能运行的问题。(Read Zhang Zhengyou calibration, data processing. Add a small amount of notes on the basis of Simon, a new version of Levenberg-Marquardt cannot run to correct the problem.)

This is a code of Pseudo-Arc Length Continuation Method , the method can be used for solving the nonlinear equations, the principle can re found in some text books. In the code,I prove the agreement of the code with other methods

围绕粒子群的当前质心对粒子群重新初始化.这样，每个粒子在随后的迭代中将在新的位置带着粒子在上次搜索中获得的“运动惯性”（wvi）向Pi，Pg的方向前进，从而可以在粒子群的运动过程中获得新的位置，增加求得更优解的机会.随着迭代的继续，经过变异的粒子群又将趋向于同一点，当粒子群收敛到一定程度时又进行下一次变异，如此反复，直到迭代结束.(particle swarm around the center of mass of the current PSO reinitialization. Thus, Each particle in the next iteration will be in the new location with particles in the last search was the "inertia" (wvi ) Pi, Pg orientation, and thus can PSO course of the campaign was a new position, increase seek better solutions opportunities. With the continued iteration, after variation of PSO will tend to the same point. When PSO converge to a certain extent when the next variation, so repeatedly, until the end of iteration.)

一个对信号进行滤波（低通、带通、高通）的教学实验数据处理演示程序。(Matlab demo program of signal filtering for instruction experiment.)

空时编码仿真源码，从专业网站上搜索的，希望对大家有用(space-time simulation source code, from a professional web site search, I hope it may be useful to)

二次规划为非线性规划的一种，若某非线性规划的目标函数为自变量x 的二次函数，约束条件又全是线性的，就称这种规划为二次规划。 (Quadratic programming as a nonlinear programming, if the objective function of a nonlinear programming quadratic function as independent variable x, and the constraints are all linear, call this plan for quadratic programming.)
